Hi emacs-devel,

I need to compare debian-like version numbers, in which 1.0 < 1.0dev < 1.1:

$ dpkg --compare-versions 1.0 lt 1.0dev; echo $?
0
$ dpkg --compare-versions 1.0dev lt 1.1; echo $?
0

My instinct would be to write this:

(let ((version-regexp-alist `(("dev" . 0.5) ,@version-regexp-alist)))
  (and (version< "1.0" "1.0dev")
       (version< "1.0dev" "1.0.1")))

Is it ok to use floating point numbers in version-regexp-alist?  Otherwise, do we have a facility to parse Debian version numbers in Emacs?

Thanks!
Clément.
